“I’m sending a POST request to https://api.vapi.ai/v1/calls and getting a 404. Has the endpoint changed? What's the correct URL to programmatically trigger a call from an assistant?”

The correct URL to trigger a call is:

POST https://api.vapi.ai/call

Here's a sample cURL request:

bash
curl -X POST https://api.vapi.ai/call \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{}'

The /v1/calls endpoint does not exist, which is why you're getting a 404. [See official docs](https://docs.vapi.ai/api-reference/calls/create?explorer=true) Source: - [Vapi API Reference: Create Call](https://docs.vapi.ai/api-reference/calls/create?explorer=true)

checking if this is resolved/solved for you?

The correct API URL is [https://api.vapi.ai/calls](https://api.wapi.ai/calls), not v1/calls.
